Bojooo

I am a small 3bb winner with poor volume at 50z and I feel very uncomfortable with my game lately. I want to move up but need to cashout frequently. I have flopzilla but didn't put much thought into it. I bought Applications of NLH'em by Matthew Janda, but after I saw some bad comments and reviews I left it. Should I buy CREV and start to balance my game or there is no need for that at 50nl. In the past I watched tons of videos (and still do watch some) but I feel the information is too chаotic(same is my post). I look into some hands in the forums but never post. I have never been in skype group(does it hep) and don't talk about poker with no one, just passively learning from some posts in the forums. What is your way of learning the game or are you like me?

year so far (10% is 100z)
